[rtl] RTLinux not unmasking XT-PIC interrupt 9
I'm observing that beta11 is not unmasking IRQ 9 after the
RT interrupt is serviced. This is on a UP pentium 90, and
the card is a PCI 3c905b, with level triggered interrupts,
at least, when it is connected to an IO-APIC. The observation
is that printing inb([0x20,0x21,0xa0,0xa1]) shows that
irq 9 is masked, and also pending.
It works perfectly well when using a regular interrupt.
Any pointers? And yes, I'm planning to upgrade later
today.
